Road Vehicles — Disturbances Test Methods for Electrical/Electronic Component from Electrostatic Discharge

GB/T 19951-2019英文版/English/翻譯

1 SCOPE

This Standard specifies the test methods for determining the immunity of vehicle electrical/ electronic components (ESA) to the electrostatic discharge (ESD) which is liable to occur during the assembly/maintenance process and caused by driver and passenger inside and outside, including the tests for components and complete vehicles.

This Standard is applicable to the electrical/electronic components for Categories M, N, O and L vehicles, regardless of the vehicle propulsion system, e.g. spark-ignition engine, diesel engine and electric motor.
